To handle these issues, we report a novel, to your best of our knowledge, SERS system that combines graphene oxide (GO) and cellulose composite paper with colloidal gold nanoparticle (Ag NP) ink. As an efficient substrate, the GO and cellulose composite paper that features hierarchical micro-nanostructures and improved discussion with target molecules may be fabricated on a large scale, plus the Ag NP ink may be really saved, preventing being oxidized in ambien
